Claims

1. A device with modular assemblies for inspecting a container, comprising a first cab assembly (2) comprising a radiation source for generating a beam of penetrating radiation for penetrating into the inspected container, a second cab assembly (6) comprising detectors (10) for detecting a penetrating radiation beam, penetrating through the inspected container, and for the formation of the corresponding radiographic signals, while the second cabin node (6) and the first cabin node (2) are located opposite each other on both sides of the viewing a walkway, a portal unit (3, 4, 5) connecting the first cabin unit (2) and the second cabin unit (6) and forming a portal frame made with the possibility of being in a position covering above the inspected container, means for moving the frame relative to the inspected container along the viewing passage, as a result of which the detectors (10, 11, 12) receive a beam of penetrating radiation generated by the radiation source and passing through the inspected container, thereby continuously looking at the container and forming a corresponding guides radiographic signals, wherein the first cabin assembly (2), the second cabin assembly (6) and the gantry assembly (3, 4, 5) are designed as modular units with the possibility of quick and easy assembly and disassembly on the viewing platform.

2. The device according to claim 1, in which the portal node (3, 4, 5) contains a horizontal beam (4) and two nodes of the vertical auxiliary supports (3, 5), connected with the possibility of disassembly with opposite ends of the horizontal beam (4) on their upper ends, and with a first cab unit (2) and a second cab unit (6) at their lower ends, respectively.

3. The device according to claim 1, in which the means for moving the frame contains running wheels (7, 7), mounted for rotation in the lower parts of the first cab assembly (2) and the second cab assembly (6), and drive means (9) to bring the running wheels into rotation (7, 7).

4. The device according to claim 3, which also contains rails (8) for the direction of movement of the running wheels (7, 7).

5. The device according to claim 2, in which additional detectors (11, 12) for receiving a tilted beam of penetrating radiation penetrating through the inspected container and for generating corresponding radiographic signals, respectively, are provided in the vertical auxiliary supports (5) and the end of the horizontal beam (4) near the second cabin unit (6).

6. The device according to claim 1, in which the radiation source is an electronic linear electron accelerator or radioisotope.

7. The device according to claim 1, which also contains at least one operator's cabin for controlling the device.

8. The device according to claim 7, in which the first cab assembly (2), the second cab assembly (6), the portal assembly (3, 4, 5) and the operator's cab assembly have dimensions that correspond to road transport.
